The results of the surveys regarding the growths of the main tree species in the Kyushu University Forests in Miyazaki District and vicinity are shown in Fig. 16 "Comparative Table of Total Volume" and Fig. 17 "Comparative Table of Volume Growth." As seen in the tables, SUGI (Cryptomeria Japonica D. Don,) is the most vigorousin growth, followed by AKA MATSU (Pinus densiflora Sieb. et Zucc.) and MOMI.(Abies firma Sieb. et Zucc.) SUGI occupies relatively small area per tree and is the most promising in the stand growth, and MATSU and MOMI are also promising species of good growth if the location is properly selected. With respect to MOMI, however, it has a drawback in that it takes long in growing the seedling. Therefore, at the present stage, it is necessary to study into rapid methods of growing the seedling. KIHADA (Phellodendendron amurense Lupr.) is a promising species inthat both wood and bark are utilized, but the other species do not appear to be promising. Though not included in this survey, the growth of HINOKI (Chamaecyparis obtusa Sieb. et Zucc) was good in the forests planted with HINOKI of 25 years of age or younger. In view of the elevation and other conditions of the Kyushu University Forests in Miyazaki District, HINOKI seems to be a very promising species for planting.まえがき I 調査の目的 II 調査の方法 III 調査対象樹種および本数 IV 供試材採取地の環境および調査結果について V むすび 参考文献
